Airtac MAC Stainless Steel Mini Air Cylinder MAC25X120SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X120SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 120mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.

About the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X120SCM
Behind the CM round-end cover is a rolled-in pivot eye, handy when the MAC25X120SCM works through a clevis or link rather than a straight push. The 25 mm bore turns 0.5 MPa into 245.3 N of forward force and 206.1 N retracting, and twin cushion screws soak up end-of-stroke shock so you can run the 120 mm stroke at pace without hammering the covers.
Its round stainless barrel is riveted to aluminium covers - a sealed shell that tolerates wet or dusty plants where painted minis flake. The 10 mm hard-chrome rod carries an M10x1.25 thread. A magnet ships inside every piston, so CMSG, DMSG and EMSG switches mount straight on. In practice, budget about 147 N for real work at 0.5 MPa, which lifts roughly 12 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC MA-series datasheet. Barrel: stainless-steel tube (round-body, riveted rolling-packed construction); piston rod: carbon steel with 20µm hard-chrome plating; covers: aluminium alloy. Thread options: PT (blank) / G / NPT. Every MA-series cylinder ships with a built-in magnet for CMSG / DMSG / EMSG position sensors.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X120SCM Is Used
Bottle reject pusher
Knocks underfilled bottles off a filling monobloc lane, with the round-end clevis link absorbing the swing of each kick.
Hopper slide gate
Opens and closes a slide gate on a small powder hopper through a clevis, letting the gate travel slightly off-axis without binding.
Clamshell forming press
Closes a blister tool then retracts to release the formed pack, the pivot eye accommodating the mould's opening arc.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X120SCM the Right Cylinder?
If 245 N at 0.5 MPa leaves you short, the 32 mm bore makes 402 N; if it is overkill, the 20 mm bore's 157 N cuts air consumption. This is a free-moving double-acting unit - cut the air and the piston coasts - so lock any suspended load with a pilot check valve or rod lock. FA flange, LB foot and SDB pivot brackets cover fixed and pivoted frames alongside the CM cover.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) is standard for sensors
- ✓ Back cover (CA/U/CM) & mount (FA/LB/SDB)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MAC Stainless Steel Mini Air Cylinder MAC25X120SCM FAQ
Push is 245.3 N and pull 206.1 N at 0.5 MPa. Step up to 0.7 MPa and they reach 343.4 N and 288.5 N; the theoretical ceiling is 50 kgf at 1.0 MPa. It breathes 40 um filtered air between 0.15-1.0 MPa (22-145 psi), travels 30-800 mm/s, and threads its 1/8 inch ports into a 25 mm stainless barrel.
Yes - every MAC25X120SCM leaves the factory with the piston magnet already fitted, so CMSG, DMSG and EMSG sensors clip into the barrel groove with no special build or waiting period. That makes end-of-stroke confirmation a plug-on job rather than a redesign.
